An extraordinary fish die-off in Lake Huron made headlines in 2025 when millions of gizzard shad accumulated near Bruce Power’s nuclear generating station, overwhelming the plant’s cooling-water intak...

What does fisheries monitoring look like beyond the datasets and research papers? For students Nash and Mason, the answer recently meant heading out on Lake Erie with the Lake Erie Management Unit cre...

A new study finds biodiversity acts like natural insurance, helping ecosystems withstand climate change, habitat loss, and other threats.

For decades, yellow perch have been an important part of Lake Erie’s ecosystem, supporting both commercial and recreational fisheries. But in recent years, yellow perch productivity in the lake’s cent...

The Centre for Ecosystem Management (CEM) is pleased to celebrate Dr. Tim Fernandes as he begins an exciting new chapter in his career as a Research Scientist with the Ontario Ministry of Natural Reso...

Researchers from the Centre for Ecosystem Management (CEM) at the University of Guelph recently led discussions on an emerging ecological concept at the annual meeting of the International Association...

New research led by one of our postdoctoral fellows, Dr. Kaleigh Davis, takes a step toward a more predictive understanding of network interactions in the face of climate warming by combining Modern C...

The Centre for Ecosystem Management recently met with the Lake Erie Management Unit last month to share updates on ongoing and planned research activities and to learn more about the MNR’s Lake Erie p...

New research led by ecologists at the Centre for Ecosystem Management (University of Guelph) is arguing that ecosystems are far more fluid than we once believed. In a changing world, ecological networ...

Predicting how species will respond to rising temperatures is still a major challenge in ecology. A big part of this comes down to understanding how temperature affects how well organisms function, es...

A recent informal postdoc symposium brought together our ten researchers for a fast-paced, idea-rich day built around short, focused presentations that sparked questions and discussion.

We are delighted to announce that our own Dr. Joey Bernhardt has been selected as this year’s recipient of the Stevenson Lectureship Award in recognition of her exceptional scientific leadership a...

Every week at the Centre for Ecosystem Management (CEM), our postdoctoral fellows (PDFs) gather for a standing meeting that’s part think tank, part sounding board, and part creative laboratory.

A day of outdoor exploration, wildlife sightings, and freshwater science came to life as some of our postdoctoral fellows led a hands-on outreach event for local youth on the Saugeen Peninsula.

Every ecosystem relies on its primary producers, the organisms that capture sunlight and turn it into energy for others. Their traits—how efficiently they photosynthesize, how quickly they grow, and h...

The 40th annual Neyaashiinigmiing Traditional Pow Wow brought together community and culture in early August in Cape Croker, attracting several hundred attendees from multiple states and provinces.

At the Centre for Ecosystem Management (CEM), we believe that science grows stronger when knowledge is shared. That’s why we advocate for open data practices across ecological research and environme...

Global warming is crossing dangerous thresholds sooner than expected with the world’s coral reefs now in an almost irreversible die-off, marking what scientists on Monday described as the first “tipping point” in climate-driven ecosystem collapse.

Scientific Reports - Multi-species eDNA as a screening tool to facilitate early detection and eradication of aquatic invasive species in large water bodies

Lake Superior is the last holdout against invasive mussels that have plagued the Great Lakes. Scientists fear climate change threatens its fate

This report confirms climate change is affecting the Great Lakes region through warmer and wetter weather, greater fluctuation in lake levels and disappearing fish populations.

We’re excited to welcome our newest postdoctoral fellow, Dr. Megan Szojka, to the Centre for Ecosystem Management (CEM)!

Freshwater ecosystems are under growing pressure from human activities like development, climate change, and pollution. But how do we know when fish are most at risk—and how can we use that knowledge ...

A new study co-authored by the Centre for Ecosystem Management’s Dr. Kevin McCann reveals that agricultural land use—especially nutrient runoff and the loss of streamside vegetation—is reshaping how e...

Bridge Michigan reporter Kelly House is highlighting a distressing trend: lake whitefish (or adikameg , in the Anishinaabe language) — once a staple in the diets and culture of those living along th...

As the planet faces unprecedented environmental change, understanding how ecosystems respond is increasingly important. A new study, co-authored by the Centre for Ecosystem Management’s Charlotte Ward...

The Government of Canada announced 26 projects receiving funding under the Great Lakes Freshwater Ecosystem Initiative.

When we talk about climate change, we often think in extremes—heat waves, vanishing glaciers, and species on the brink. But nature’s responses to these shifts are far more nuanced, and according to a ...

You don’t always need massive datasets to learn something important about nature. While modern ecology often focuses on large-scale “big data,” a recent study carried out, in part, by one of our colla...
